Well, quick and with no guarantee ;-) there are two steps necessary, I assume:
1) Get a list of all the objects you need. If you are in folder products/music,
maybe with:

<dtml-in "books.objectValues([])">
</dtml-in>

or with

<dtml-with books>
   <dtml-in objectValues>
   </dtml-in>
</dtml-with>

2) Now you can test, if the property exists, f.e. with

     <dtml-if menu>
     </dtml-if>

Didn't test it, but I hope the principle is clear,
